Is their away to fix widows registry errors without reinstalling widows?

Like the topic says one of my desktop PC’S had posting issues where when turning the PC on it would shut off after posting I managed to fix the issue by taking out the ram and reinstalling it, but now my desktop has a ton of registry errors and windows takes like 5 minutes to boot is their away to fix them without doing a fresh reinstall?

Hmm, I'm not sure about this but why not try using some utilities that fix the registry of PCs like Advanced System Care? I'm not a technical kind of guy so I use these kinds of utilities to fix problems on my PC.

You could try doing a simple registry clean with something like CCleaner. If you know the specific application that was causing the problems, you could use something like Jv16PowerTools to search for all instances in the registry related to it and remove those. I did this recently when all my Adobe apps started crapping out on me. I had to remove everything Adobe, and clear all registry entries mentioning Adobe in them.
